Continental Defence Corvette

[Maxman1]

Would it be so outlandish to suggest dusting off the plans for the HALIFAX class and knocking out 8-9 new build versions?

Finland's new corvette is basically a modern Halifax, with ice strengthening and VLS.

Originally I discounted this as a reference ship but I'm coming around. The ice resistance and general weapons with sensor loadout is pretty good.

A Canadian version would need much longer range/endurance, and better oceanic seakeeping. It would also likely be more modular.

Crew size of 70 is pretty close to what we would want as well.

Basically it means saying that "we're going to buy a MOTS design and only change like, 15% of it", but then proceed to incrementally change more and more until 85% has been modified from the original design.

Oh you mean "Canadianization"

Halifax Class 134m x 16.4 x 4.9m at 4735T Range 9,500NM

Pohjanmaa Class 177m x 16m x 5m at 4300T (Ice Class 1A) Range 3,500NM

I think the biggest issue with this class is it puts the construction back onto 1 of the 3 NSS shipyards and mostly excludes the smaller yards.

 

[Underway]

Not if it's a team build. Smaller yards build blocks and ship them to the larger yard for assembly. It's how you speed up the build and include those smaller yards.

I guess that’s why I was thinking HALIFAX class as a starting point, particularly since the FELEX stuff was as non USA as possible at the time. Also, not trying to name drop here, but I once had a chance to chat with John Newton and he was very eloquent in his praise of the seakeeping capabilities of the CPF. I know the class has shortcomings when compared to modern peer frigates, but I thought maybe its benefits would outweigh those in use as a CDC (with closer to home roles). I guess the ice strengthening would be an issue, though.

What we don't have is the creativity/experience in ship design or the breath of experience in alternative materials (like composites). We have ship designers that can adapt other designs, but clean sheet a warship with creative and applicable solutions (like the FDI above), thats probably beyond us right now.

Presumably it wouldn't be the RCN making the design itself, but it would be a clean sheet design contracted out to a partner like Vard most likely, maybe Davie (big maybe on a clean sheet warship design given their experience). Topshee has been fairly clear that he wants our own design to avoid the headaches that come from adapting/adopting somebody elses.

Russia is keeping its helicopters away from Ukraine's naval drones, a special forces commander says. They were becoming 'easy targets.'

Russia is using helicopters to try to stop Ukraine's drones. Now its naval drones armed with missiles keep Russia's helicopters away, per a commander.

Is this integral to the CDC platform design or an adjunct?

Is every CDC a traditional, stand-alone island fortress, or does it always sail in its own mini-taskforce?

At the time the CPF was constructed and initially in service it was likely the worlds best true General Purpose Frigate. The missions for the CDC are not the missions for the CPF and the CPF needs a lot of crew. The idea for the CDC is that you can crew three CDC with the same numbers as a single CPF.

There will likely be CPF DNA in the CDC though. Lots of tech developed for the CPF will end up in the CDC.

s every CDC a traditional, stand-alone island fortress, or does it always sail in its own mini-taskforce?

Who knows at this point. Its still an idea on paper. Probably both, that's the thing with ships, they can form teams or sail on their own... lol

It's 117m, not 177. That's only 12m over the target length, which is likely not a hard limit. And ice strengthening increases the weight.

 

[Rainbow1910]

It's also something to consider that Topshee specifically said this vessel will not be an icebreaker, but will be ice strengthened for operations in/around ice equivalent to Polar Class 6~. They can get away with some savings over an actual icebreaker at those sorts of levels and they will definitely have weight gained, but it's a light enough rating that it shouldn't be an impossible circle to square.

Although comparing ice ratings are difficult, it seems that the Ice Class 1A rating of the previously mentioned Pohjanmaa-class corvette roughly compares to Polar Class 7, meaning a Polar Class 6 vessel would be rated even higher than the Finnish corvette.

Polar Class 6: Summer/autumn operation in medium first-year ice which may include old ice inclusions, ice of 70 to 120 cm (2.3 to 3.9 ft).

AOPS is Polar Class 4 on the bow/stern and Polar Class 5 on the rest of the hull, the new Canadian Coast Guard Offshore Oceanographic Science Vessel CCGS Naalak Nappaaluk is also rated for Polar Class 6.

I recently found my cassette

Well, I just recently found my copy of Tears For Fears “Songs From A Big Chair” on cassette. Plays as sweet as it did in 86. I have a right to be optimistic…

Have you ever tried to listen to “Head Over Heels” with crackle in the playback?? The stakes are higher than you think…

I am intrigued by this new entry into the arctic harbour sweepstakes,
Qikiqtarjuaq

‘That’s our vision:’ Qikiqtarjuaq prepares for its long-promised deepsea port

Newspaper of record for Nunavut, and the Nunavik territory of Quebec

nunatsiaq.com

It is on the east coast of Baffin Island, has a deepwater approach, unlike Iqaluit, and has a relatively short seasonal icefield to breach before it accesses open water.

It also advertises itself as a potential fishing port. I know that the Danes and Norwegians have shrimping those waters for years in factory trawlers, some of which are marginally ice-strengthened.

Port infrastructure build is to commence in 2026. It intends to compete with Nuuk and St John's for the fish trade.
